Product details

Overview

The C25F4D is a Schneider ComPacT NSX250F DC basic frame rated 250 A with a 36 kA breaking capacity at 750 VDC, built for 4-pole DC distribution in a fixed-mount toggle-operated package. It is a bare frame without a trip unit, designed for DC networks and compliant with EN/IEC 60947-2, with a 750 VDC insulation rating and suitability for isolation.

For a line-down or last-time-buy situation, an RFQ confirms available quantity and lead time from our multi-source network.

Against the 3-pole C25F3D (NSX250F DC, 250 A, 36 kA), the C25F4D adds a fourth pole for DC circuits requiring a switched neutral or full 4-pole isolation — the C25F3D fits when the BOM specifies 3 poles.
